Application filed June 1, 1920. Serial No. 385,410.

To @El whom t may conce/rn Be it known that I, Louis V. HOMAN, a citizen of the United States, residing at South Dartmouth, in the county oi Bristol and State of Massachusetts, have invented new and useful improvements in Conduits 'for Power-Transmitting Cables, ot which the following is a specification.

IThis invention relates to power-transmitting means including a flexible cable at-` tached at one end to power-driven means, whereb it ma be moved longitudinally, the cab e exten ing from said power-driven means in an angular path, so that portions of the cable move in different directions.

The invention is embodied in the improvements which l will now proceed to describe and claim.

Of the accompanying drawings forming a part of this speciication,

Figure 1 is a side elevation of a portion of a conduit embodying the invention, and portions of a cable guided by said conduit.

Figure 2 is an edge View of a portion of the conduit, having a somewhat diiferent arrangement from that shown by Figure 1.

Figure 3 is a section on line 3 3 of Figure 2.

Figure 4 is a side view of a portion of a conduit, which may be equipped with a pair of pulleys.

Figure 5 is a section on line 5--5 oi' Figure 4.

Figure 6 is a side view, showing a different arrangement embodying the invention.

Figure 7 is a section on line 7.7 oi Figure 6, and a plan view of the parts below said line.

Figure 8 is a top plan view of a portion of the conduit shown by Figure 6.

The same reference characters indicate the same parts in all of the figures.

My improved conduit as shown by Figures 1 to 5, inclusive, includes an angular conduit member comprising a hollow or cupped body forming a pulley chamber 13, and composed of a central portion 12, forming one side of the chamber 13, and an annular wall portion or flange 12c forming the margin and open end of the chamber. The wall portion 12C is provided with tubular conduit nipples 16, tangential to the chamber 13, and angularly arranged relatively to each other. Said nipples communicate with the chamber and are adapted to be coupled to conduit tubes 17 preterably by being internally threaded to engage threads on the tubes 17. The wall portion 12c is also provided with an internal screw-thread 19. The open end of the pulley chamber is closed at the side opposite the central body portion 12, by a detachable cap 18, including an annular portion 18C, having a screw-thread 20, adapted to engage the thread 19 of the body. 'The cap 1S provided with a hexagonal boss 21, adapted to be engaged by a wrench.

To the central portion 12 is rigidly secured a stud 14, forming a iiXed bearing on which a pulley 15 is removably 'journaled, the pulley being arranged to guide a cable 22 from one nipple 16 to the other.

Owing to the :fact that the stud 14 is rigidly attached to the hollow body, and supports the pulley independently of the cap 18, the 'cap may be removed without depriving the stud of any part of its support, so that the stud remains in place, and does not have to be handled or touched by the operator when the conduit member is opened. The pulley may be lubricated without removing it from the stud, or it may be conveniently withdrawn `from the stud, lubricated, and replaced on the stud.

The screw-thread connection between the cap and the body enables the cap to be quickly and conveniently removed and replaced, by rotation of the cap, and forms a continuous water-tight joint between the body and the cap.

The angularity of the nipples 16 relativel to each other, may be varied. Said nipp es may be arranged so that their longitudinal axes arey at an obtuse angle relatively to each other, as shown by Figure 1, or at any other desired angle. The cap 18 coniines the pulley in place in the chamber 13. 1When said cap is removed, access is permitted to the pulley Jfor the purpose of lubricating or removing the same, the stud 14 remaining in place when the pulley is removed.

When the axes of the nipples 16 are substantially at right angles with each other as shown byk Figures 2 and 4, the body 12 may be provided with ears 23, adapted to receive attaching screws securing the said ears to iiXed supports.

As indicated by Figures 4 and 5, the chamber 13 and stud 14 may be formed to accommodate' two pulleys 15 located side by side and guiding the two cables 22, the nipples 16 bei-ng'formed to accommodate the two cables, as indicated by Figure 5.

Figures 6, 7, and 8 show a somewhat different embodiment of the invention, inv

which the bod f is composed of two portions 12 and 12a, o set from each other, the portion 12a forming an additional open-sided pulley chamber 13a, and provided with an additional stud 14a, an additional pulley 15, a detachable cap 18, and an additional nipple 16a. The arrangement is such that the pulleys are adapted to guide two flexible cables 22 and 22a from one nipple 16 in opposite directions, one cable passing through the other nipple 16, and the other cable passing through the additional ,nipple 16u lt is obvious that the vcomplete ,conduit may include any desired number or body.

portions 12 having end portions' 16, these being connected by tubular portions 17 to form a conduit having any desired arrangement.
